A key turn-around event around infrastructure has been the virtualization of servers. We were told how this is good for performance, isolation and optimal use. However, I noticed with several of our clients who chose to use bare-metal servers citing performance gains, a particular client was running an OpenShift cluster with the master nodes on VMs but application nodes on bare-metal. Is this a trend? What are the implications? Are we turning away from VMs?

While Bare-metal does offer some performance and other benefits and its use has risen, not so with Kubernetes. To quote from a recent survey "While Kubernetes is widely adopted in the enterprise today, the percentage of workloads running on Kubernetes remains comparatively light. Even fewer of those workloads are running on bare-metal servers versus virtual machines. "

Some of the limitations of bare-metal are absence of integrated services such as load balancers that cloud environments provide. But that does not imply bare-metal doesn't have any advantages, which it does as noted at https://www.ericsson.com/en/blog/2020/3/benefits-of-kubernetes-on-bare-metal-cloud-infrastructure
